3M™ Scotch-Weld™ Acrylic Adhesive DP8425NS is a non-sag, two-part acrylic adhesive. This tough adhesive offers improved adhesion to many plastics and metals, including those with slightly oily surfaces. It is a durable product that features a fast rate of strength build to provide structural strength in just minutes.3M Scotch-Weld Acrylic Adhesive DP8425NS is a non-sag acrylic adhesive with a 10:1 mix ratio. It features a 23-minute work life to allow time to position substrates prior to adhesion. This working life, open time and cure time can be accelerated with heat. Once fully cured, this adhesive will reach 1,000 psi (7 MPa) of overlap shear strength in approximately 53 minutes, increasing throughput and productivity while featuring a high peel and impact performance. Full cure will be reached within 24 hours. 3M Scotch-Weld Acrylic Adhesive DP8425NS green has been recognized by Underwriters Laboratories (UL) for use in electrical equipment and electric signs. Please review UL File QOQW2. MH17478 and Sign Components Manual (SAM) File E464624 for details. 3M Scotch-Weld Acrylic Adhesive DP8425NS should yield similar results as 3M Scotch-Weld Acrylic Adhesive DP8410NS Green, which has been tested for surface flammability, smoke, toxic gas generation, and caloric content.
